ABSTRACT: The blood supply to the most of abdominal organs is provided by the
branches of CT. The SMA supply caecum, ascends colon, all of the small bowels except the upper
part of duodenum. Knowledge of variable anatomy of celiac axis and SMA may be
useful in planning and executing radiological interventions such as
celiacography and chemoembolization of hepatic and pancreatic tumors. In this
study, the uncommon or low percentage cases of CT and SMA are presented in the
light of clinical and embryological information. The celiac axises of a total of
30 adult corpses were examined. Dissections
of abdominal region were performed in detail according to Cunningham’s manual. Angiographic images of 100
consecutive adult patients who underwent celiac MDCT angiography were evaluated.
During autopsies, an incomplete celiac trunk or bifurcation of celiac trunk
associated with the hepatomesenteric and
gastrosplenic trunks (0.7%) and a celiacomesenteric trunk associated with high origin superior mesenteric
artery and gastrosplenic trunk were detected (0.7%). During MDCT
angiography, a case of total absence of celiac trunk associated with a
hepatosplenomesenteric trunk (0.7%) and also a case of total absence of
celiac trunk alone were observed (0.7%). The persistence or unusual development of ventral
splanchnic arteries (VSAs) or ventral longitudinal anastomosis may result in
variations or the unusual trunks related to celiac axis and SMA. The anomalous trunks of
the CT may be result of either the persistence of some parts of the VSAs or
ventral longitudinal anastomose that normally disappear or disappearance of
parts that normally persist. The prevalence of unusual trunks of celiac axis
and SMA in this study is quite low in literature. These abnormal vessels pose problems for
surgeons and radiologists. Such vascular anomalies may cause clinical
complications following surgical and radiological procedures such as resection
of tumor of the pancreatic head, lymphadenectomy, coeliacography, aortic
replacement with reimplantation of the trunk and coembolization of pancreatic
and liver tumors.
